RELAY.

Specification of Letters Patent.

Patented Mar. 16, 1920.

Application led February 2, 1917. Serial No. 146,059.

T 0 all 'whom t may concern Be it known that I, lViLLiAM KAISLING, a citizen of the United States of America, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Relays, of which the following is a specification.

My invention relates to electromagnetic relay structures and has more particularly to do with structures of the kind that are provided with a circuit changing spring movable to an off-normal position upon one operation of the electron'iaguetic structure and returnable to normal position upon a second operation of the electromagnetic structure.

The structures of thek prior art which accomplished the above results have all been cumbersome, inefficient structures, most of which were provided with a pair of electromagnets, one electromagnet operating to inechanically lock up its armature when it energized and a second electromagnet operating to mechanically unlock the armature of the first electromagnet when it energized. It is devices of this kind which I have had especially in mind in developing my invention. y i

An object of my invention is the provision of an improvetL device of the class above described including an ordinary telephone relay provided with a single operating electromagnet and armature.

It is a further object of my invention to produce an improved device which obviates all the undesirable features found in the structures of the prior art and embodies desirable features and advantages all in a simple, efficient and Aeconomical manner; and to the accomplishment of this object and such others as may hereinafter appear, my invention consists in the novel details of construction, parts and combination of parts hereinafter described, and particularly pointed out in the appended claims. l

I will now refer to -the accompanying (,lra'wing in which I illustrate one embodiment of my invention. The like reference characters in the different views denote like parts and in which- Figure 1 is an elevation of the relay structure of my invention showing the contact springs in one of their positions;

Fig. 3 is a right end view of Fig. 1;

Fig. fl is a view showing the contact springs in an alternate position to that shown in Fig. 1;

Fig. is an enlarged fragmentary sectional view showing one method of mounting the interrupter disk, and

Fig. 6 is an enlarged view of the interrupter disk.

Referring now more in detail to my invention as illustrated, it comprises a magnet coil A wound upon a core 1, which provided with spool heads 2 and 3 mounted upon it. An angular heel iron 4f is provided, an arm of which extends forward parallel to the core 1 of the coil A to the front end of the same and serves to extend one pole of the magnet to the frontend of the structure. The core 1` has a screw threaded extension 11 which extends through suitable openings or orifices in one arm of the heel iron 4 and in the mounting plate The coil A and heel iron e as a whole are securely held to the mounting plate 5 by means of a nut 6 which has screw threaded engagement with the extension 1l of the core 1. Terminals -7 and 8 for the coil winding are suitably fastened to the spool heads '2, and extend through suitable openings in the An armature 9 `is pivetally mounted upon the metallic spool head il by means of a hinge 10 suitably fastened to the said non-magnetic head by means of screws 11. 'A screw threaded stud 12 suitably fastened to the forwardly extending portion of the heel iron 11 carries a split nut 13 having screw threaded engagement with the said stud 12. A suitable orifice 111 in the armature 9 is provided for the passage of the said stud 12. This nut 13 in conjunction with the stud 12 allows adjustment to limit the throw of the armature 9.

An interrupter disk M is rotatably mount ed upon the forwardly extending arm of the heel iron el by means of a stud 15 fastened to the said heel iron d in any suitable manner` A cylindrical member 16 is rotatably supported by the pin 15 and is provided with a pair of flanges 161 and 162 which secures the disk M to the shank 16. The cylindrical member 16 rotatably supports the disk M and serves as a 'bearing for the same. A ratchet R is oiined integrally with the disk 1v1 by ineens ot a shearingL operation, that is, thek instal of the disk to form one of the teeth 17, is ruptured on three sides as at 18, 19 and 2O and then the free portion 21 is pressed down to form the tooth, as clearly illustrated in Fig. 5, thus leaving a recess into which the paivl The pawl 22 is pivotally supported upon the armature 9 by means of the pivot pin` :.3 which passes through the ears 91 and 92 formed integrally with the armature, and provides means for rotatably stepping` the disk M, step step, as will be presently described. A tension spring' 2li ser to vreep the nose 22l oi' the paivl in engageVV nient with the ratchet of the dish. The spring 2e is fastened at its one end to the hinge, 1G by means ot one of the screws lL The free end 241 ot the tension spring rests against the angular portion 2:42 or the paWl 22 and is held in place by the turned over portion Y 224 and 2270i: the pawl .i plurality of depressions or recesses and are formed or punched in the depressions being ot a ,greater depth than those bearing the reference numeral 2G tor a purpose to be hereinafter explained.

A .plurality t teeth are 'formed upon the periphery ot the dist: M and in conjunction with the downwardly turned portion 223 of the parvl acts as a check or stop so that for each attraction ot the arinature 9 the paivl 22 steps the disk one step only, and upon the 'full attraction of the :irinature 9 the part 22"; engages a tooth 2S, thus preventiifigl an over-run operation oit the disk M due to its inoinent nl caused by the pawvl strikinil the disk. Two sets oit' contact springs 30, 31 and insulatingly mounted upon the heel iron tie by means oi: the screws 33. rlhe terminal ends ot' the springs extend through a reress in the mounting plato The Contact f oi'- each set is provided with an ii stud or button Sel mounted upon its eein free end and extendi Tardly. rounded end ot the butn Sie ists in either a depression 25 or a depression as cese may be. fi cylindrical casing il() is provided to inclose the entire relay a 'l has screw tlireaded engagein mt with three. ls on the n1cuiutiiegL plate 5.

For the purpose ot' illus/ration, l have shown a make and break combination. ot

'contactsprings but it is to be understood contae; springs 30 and troepen m contact springs 3l and B2 are closed. New,

' dish lv" when an impulse oi current or a circuit is closed through the Winding ot magnet EL, the elec'troinagnot attracts its armature 9 and causes the paWl 22 to rotate the interruptor ough the space ot one tooth only, due to the engagement ot portion ot pawl with tooth 2S upon the peripheryv oi' the disk M, as previously described. rl'his movement oi the dish M causes the dopressions to be stepped 'troni under the buttons or button and to bring shallower depressions 2G in position under the buttons 94;. l/TJhen in this position, the contact spring 31 is forced into engagement with the contact spring, 30 and disengages the contact spring 32, as illustrated in Fig. 4. Upon the next ouergization of magnet A, its armature 9 is again attracted causing` the pavvl 22 'to thrust the disk l another step in the saine manner as previously disclosed, causing the depressions 26 to inove from under the buttons 3e and place the depressions in position under the buttons Se. 'lfhc depressions 25, being of a greater depth than depressions 26, permit the spring 31 to disengagge spring and to move into contact with spring` For each actuation ot the ,relay armature 9, a circuit change is brought about as just described.

lt will be thus apparent that l have provided a relay oii novel form and While l; have described the invention with particular reference to the details of a specific con struction, it may be readily seen that various n'iodi'ioations, alterations and substitutions may be made thereon and still coz-neV iwithin the spirit ,and scope of the appended claims. The interruptor disk M, for exainple, is shown having a certain combinaH tion oi? depressions which'operate in conjunctl sith certain Sebring coi'nbination, but is evident that theccomloination oit depressions be changed to operate in dit'- teient spring combinations and still come Within the scope ot the appended claims.
